Hey, I am currently in a situation where I have a DC output from LTC1968, and I would like to use some kind of op-amp (for example: instrumentation amplifier ) that can reduce noise and higher frequency. Below is the flowchart of the signal. My questions is:
1) Is there an instrumentation amplifier that can take one input signal (using +IN pin and probably grounding the -IN pin), since LTC1968 outputs a DC signal? Note: I do not want to use an instrumentation amplifier that has dual output; a single output is preferred.
2) Beside instrumentation amplifier, do you have any other ideas. I can think of a low pass filter; is there even a higher order low pass filter?
I hope to hear your response.
Edited for clarification
